SHINGLE-sAwlNe MACHINE.

SPECIFICATION forming part of Letters Patent No, 355,473, dated January4, 867.r

Application filed April 5, i886. Serial No. 197,910. (No model.) l

To all whom it may concern.-

Beit known that I, DERoY RILEY, a citizen of the United States,`residing at Coventryville, in the county of Chenango and State of NewYork, have invented certain-new and' useful Improvements in Shingle-Machines and I do hereby declare that the following is a full, clear,and exact description of the same,

reference being had to the annexed drawings,

IO making a part of this specification, and to the letters and figuresof reference marked thereon.

Figure l of the drawings is aperspective view of myinvention; Fig. 2, atop plan view thereof with a portion of the frame partly broken away.Fig. 3 is a vertical section taken on line x x of Fig. 2, Fig. 4., adetail view in perspective of the tilting frame, supporting bracket, camblock, and toothed wheelyand Fig. 5 a det-ail View showing the 2Orelative position of the several belt-pulleys.

The present invention has for its object to provide a simple, effective,and easily-oper ated machine for sawing shingles; and it consists in theseveral details of construction,sub

stantially as shown in the drawings, and hereinafter described andclaimed.

'Ihe dogs B are pressed out against the inner ends of the blocks by acoiled or other suitable spring, d, inclosed within a casing, e,

also connected to the sides ofi the arms b, said casing also forming aguide for the' rear end of the dog, into which it enters.w

The carriage A is connected to the upper end of a vertical shaft,g,'whieh has its bearing in the cross-beams h i of the frame of themachine. The under side of `the carriage has centrally connected to it alarge cog-wheel, O, with which engages a pinion, k, upon the end of avertical shaft, Z. The shaft Z hasv keyed 4o to it a belt-pulley, D, andis connected with a cone-pulley, E, by means of an endless belt passingaround said pulleys,F a second endless belt in like manner connectingthe cone-pulley E with a similar cone-pulley, F. These cone-pulleys areof the usual construction and employed in the ordinary manner forchanging the speed of a main'pulley, andin the present instance they areused for the purpose of regulating the speed o f the carriage byV oshifting the belt on said conepulleys, thus adapting t-he machine fordifferent work. In

order to regulate and vary the speed of the several parts, the drivingforce is primarily imparted to the cone-pulley E.

The saw G is connected to one end of a shaft, m, which has its` bearingsin the fram/e of the machine, and is provided with 'a pulley, H, aroundwhich passes the driving-belt. This pulley H is connected with thecone-pulley F by an endless belt, and by means of these endlessbeltconnections and pulleys motion is given to the shaft Z, and through themedium of the pinion k and toothed wheel C a rotary motion is impartedto the carriage.

The upper side of the carriage A is provided with a circular support, I,for the blocks from which the shingles are cut, in order to have themwithin convenient reach of the attendant to feed them to the machine,the support also vforming a brace for the carriage at its axial centerto strengthen it.

After the block is taken from the support I it is placed on a tiltingtable, K, of any suit able construction, but preferably in the form of askeleton-frame, as shown in Fig. 4, said table being retained in ahorizontal position by a spring, n.

The table K is pivoted to a suitable bracket, L, provided with a rod, o,screw-threaded at its lower end, and extends down through an elongatedslot, p, in the cross-piece q of the frame ofthe machine. The two arms rof the bracket L extend up through holes ina crosspiece, s, of theframe, and by means of the jam-nuts ton the screw-threaded end of therod o the bracket can be raised or lowered to increase or diminish itsheight with relation to the carriage, and is held in its adjustedposition by the jam-nuts above described. This adjustment of the bracketL is to 'change the position of the tilting table K, which is pivoted tothe arms r of said bracket, thereby regulating the thickness or taper ofthe shingle l and style of head, the table at all times being below thetop of the frameof the machine, so

.that the block, when taken up by the dogs B f from'off the table, willbe brought against the saw in such relation thereto as to cut therefromthe desired thickness of shingle. The' crosspieces g s, if preferred,may be hinged 'to one of the standards M of the frame of themachine, orin any other well-known manner connected roc' pieces are connectedtogether by asutable brace, u, forming a frame to which is attached, ashereinbefore described, the bracket L.

The bracket L has a bifurcated arm, N, to form bearings for the shaft ofa block, O, the shaft thereof having connected to its inner end atoothed wheel, l?. The block O acts as a cam to raise the inner end ofthe tilting frame K, and has iiat sides in number to correspond with thenumber of teeth on the wheel l?. In the present instance I have shownfour teeth, which are operated upon by pins t, depending from the underside of the carriage A, and come successively in contact with the teethas the carriage revolves, thus turning the block and bringing thecam-faces thereof against the under side ofthe table, which will tiltit.

l Although the block O has flat sides, the corners of the block act inthe capacity of cams to raise the table as they are brought against it,and therefore I shall hereinafter term the device a cam-block.

The cam-block l?, as will be noticed, is tapering, and held on the shafta by a set-screw, b', to enable said block to have its ends reversed, oito adjust it longitudinally on the shaft. The object of reversing theblock or adjusting it on the shaft is to bring a different diameter ofthe block in contact with the under side of the tilting table when theshaft a is turned, thereby regulating the extent to which the table willtilt, and `lconsequently regulating the thickness and taper of theshingle.

VThe table, as shouldl be understood, is for the purpose of bringingtheI block from which the shingles are cut into position previous tocoming ,in contact with the saw, so that each time the block is actedupon by. the saw a shingle will be cut therefrom of uniform size andthickness.

The tripping device f on the under side of the dog B, which is providedwith a frictionroller, w, is acted upon by a cam-track, R, as thecarriage revolves, said track being connected to the top ofthe frame ofthe machine, and extends about one fourth around the same.

The cam-track at its forward end gradually approaches nearer the axis ofthe carriage, so that the action of the track upon the dog will draw itfrom the block to release it before the block ,reaches the table, thusenabling the block to get in position on the table for a shingle to becut therefrom, or to be removed from the machine.

The saw G is guarded by an extension, "1l,

to the frame of the machine, which, if preferred, may be provided with atrough or any other suitable device for carrying ofi' the dust from thesaw, as in the usual manner.

A chute, U, is employed to receive the cut shingles from the saw anddeposit them in a receptacle placed under the chute, or deposit them ina pile on the door, as found desirable.

In the operation of the machine the blocks from which the shingles areto be cut are held to the frame A by the dogs B, as hereinbeforc stated.`As the carriage revolves in the direction of the arrows the trippingdevicef, with its roller w, is brought successively in fric.- tionalcontact with the inner face of the camtrvack R, which will graduallydraw in the dog and release it from the block, leaving the block free toadj ust itself on thetable K, after which it is again taken up by thedog in its adj usted position and carried against the saw G. The shinglehaving been cut from the block, the latter is carried over the sawl andaround until it is released by the cam-track R, acting on the trippingdevice f, to force in the dog, as above described, after which the blockwill be free to again adjust itself on the table K, so that a secondshingle can be cut therefrom, the dog again holding the block to thecarriage in this adjusted position by the action of the spring dimmediately on release of the dog by the cam-track, or when the dog haspassed beyond the forward end of the track. Immediately upon release ofthe block by the dog the table K is brought to the desired incline bythe pins c coming in contact with one of the teeth of the wheel P, whichturns the shaft a', and brings one corner of the cam-block O against theunder side of thc table, and in so doing raises that end, .and 4.therebythe shingle-block when received on the table will be supported at thedesired incline to cut therefrom a shingle of the required taper whentaken up by the dog and brought against the saw.

I do not wish to be understood as confining I myself to any particulararrangement of belts and pulleys for imparting to the saw and carriagcthe desired motion, as any well-known means may be substituted for thispurpose that will successfully attain the end desired, and any suitableconstruction of frame may be used for supporting theseveral parts ofAthe machine; and I reserve the right, therefrom said bracket, atilting'device inounted in said arm, a circular revolving table foractuating said tilting device, spring-dogs carried by said table, and acam-track, R, adapted to operate said dogs to drop the blocks on thetilting table and again seize them for presen-L tation tothe saw,substantially as set forth.

2. In a shingle-machine, the combination, With ahorizontally-rotatingcarriage provided with means for holding the shingle-blocks thereto andreleasing them, of a tilting table to receive the blocks, and means forintermittently tilting said table, consisting of a shaft provided withatapering cam-block adj ustable thereon, and a toothed Wheel operatedupon bypins depending from the under side of the carriage, substantiallyas and for the purpose described.

In testimony that I claim the abovel have hereunto subscribed my .nainein the presence 2o of tivo Witnesses. l
